Guest Mysta2 Posted July 15, 2010 Share Posted July 15, 2010 I cut myself some clipons for my '94 in order to better fit my RC30 glass. I would like to eventually go ahead with a full on USD front end but in the mean time what do you recommend for handling the fluid reservoirs? Can I swap out just the levers and reservoirs without swapping the front brakes entirely? And even if I do have to go full on with matching levers and brakes (and possibly forks), how would I handle the clutch? Quote Link to comment Share on other sites More sharing options...
SEBSPEED Posted July 15, 2010 Share Posted July 15, 2010 You can use whatever you want, as long as the piston bore size is the same(marked on the underside of the master). Make sure the brake light /clutch switches are compatible too. Quote Link to comment Share on other sites More sharing options...

Make sure the brake light /clutch switches are compatible too. Yes, but doesn't have to be exact, although I'd go bigger rather than smaller. The bigger the master, the more pressure down at the calipers for the same input on the lever, smaller is less... As to the brake light switch, you can get an inline version if you need to. It's a replacement Banjo with a pressure switch in it. Quote Link to comment Share on other sites More sharing options...

This will increase lever effort for a given amount of braking force. A smaller master cylinder will increase the lever ratio, thereby DECREASING lever effort for a given amount of braking force, the tradeoff being longer lever travel to accomplish the same braking load. Best to stay with the same diameter as was provided with your calipers from the factory. http://cnx.org/content/m31723/latest/ Quote Link to comment Share on other sites More sharing options...
VIFFER93 Posted September 28, 2010 Share Posted September 28, 2010 Cylinder bores must match for brakes and clutch. As far as a hydrolic clutch goes the slave cylinder "ratio" must be compatable as well. I am looking into doing a clutch resevoir conversion but I have not had the time to track down what will work. As far as the brake resevoir goes. Personally, I would wait and decide if you are going to do a front end swap. That will dictate what your braking "system" will be and you will be able to plan accordingly. But on the 3rd (I believe they are the same as 4th generation) specs are as follows per the service manual. Brake masters are (mm/inch) ; Master cylinder ID = 12.700-12.743 (0.5000-0.5017) - Master Cylinder OD = 12.657-12.684 (0.4983 - 0.04994) Clutch Master are (mm/inch) ; Master cylinder ID = 14.000-14.043 (0.5512-0.5529) - Master Cylinder OD = 13.957-13.984 (0.5495 - 0.5506) I was hoping to use an RC51 clutch master I have but the RC51 master is smaller then the VFR version.

mrmatt Posted September 28, 2010 Share Posted September 28, 2010 I've heard that the Superhawk (VTR1000) clutch is a match to the VFR, and right now I'm using a VTR brake master with my 954 front end Quote Link to comment Share on other sites More sharing options...

That clutch master will work...... It also looks like after 2004 they switched to the "coffin" style. Thanks Mr. Matt Super Hawk Clutch specs... Clutch master Cylinder specs - Clutch Master ID - 14.OOO - 14.043 (0.5512 - 0.5529) Clutch Master OD - 13.957 - 13.984 (0.5495 - 0.5506) http://www.superhawk996.net/Honda_VTR1000F_Service_Manual.pdf Edited September 28, 2010 by VIFFER93 Quote Link to comment Share on other sites More sharing options...
Member Contributer vfrjim2002 Posted September 28, 2010 Member Contributer Share Posted September 28, 2010 good info I'm with everything Rob says, with one small exception: If you're interested in changing brake feel juggling mc to slave ratios is a good way to do it. If you the brakes are too sensitive you can move to a mc with a larger piston or a different lever leverage ratio. By the same token, if you want more sensitive (in a sense more powerful) brakes you can use a MC with smaller bore. Quote Link to comment Share on other sites More sharing options...

Member Contributer JZH Posted September 30, 2010 Member Contributer Share Posted September 30, 2010 I had a remote reservoir brake master cylinder on my VTR1000F-forked RC36 for a while, but ended up going back to a "coffin" master cylinder because the remote res was always getting in the way. Bling sacrificed for practicality--I know, I have sinned! :biggrin: Ciao, Quote Link to comment Share on other sites More sharing options...

I've been running an RC51 clutch master for years w/out any issues. This is good. I might give it a try because I have one available but for brakes I think it is much more important to make sure you have things match.
